Abstract In order to improve the transmission performance of the wireless power transfer (WPT) system, the concept of the optimal receiver radius is proposed in this paper by studying the variation law of magnetic flux and inner radius of receiver coil in magnetic resonant wireless power transfer (MR-WPT) system.By analyzing the WPT system of planar square, planar round and spatial spiral transmitter coils, the inherent existence of the optimal receiver radius is revealed. The variation rule of the optimal receiver radius with the parameters of the WPT system is explored, so as to determine the parameters affecting the optimal receiver radius. On this basis, the BP neural network improved by genetic algorithm is used to learn the variation law of the optimal receiver radius with the influencing parameters, and the accurate prediction of the optimal receiver radius under different coil parameters is realized. Finally, the existence of the optimal receiver radius of the WPT system and accuracy of the prediction results of the improved BP neural network are verified by the finite element simulation and experiments.

Key words： Wireless power transfer optimal receiver radius genetic algorithm BP neural network transmission performance
